\item[$p_{ij}$]active power injection from node i to j, more specific it is the amount of power measured at node j.  \item[$B_{ij}=\operatorname{Im} (1/Y_{ij})$] imaginary part of inverse admittance matrix (or, alternatively $1/x_{ij}$, where $x_{ij}$ is line reactance).  %\item[$p_j = \sum_{u\in j} g_u - \sum_{u \in j} d_u$] active power injection in node j   \item[$k^{(i,j)}$] is the coefficient for loss modeling which is equal to $\frac{R^{(i,j)}\cdot 4}{(V_i + V_j)}$ V_j)^2}$  \item[$R^{(i,j)}$] resistance of line $(i,j)$.  \item[$V_i$] nominal voltage at bus $i$.  \end{description}
